“Someone who feels that they are surrounded by enemies on every side and is trying to find the right course to survive,” Ellen Aguiar said about her son during an exclusive interview with NBC 6.

A document executed March 5 shows that the millionaire designated his wife as guardian of his person and property and his mother as the alternate, in the event of his his incapacity. In a similar document executed just two months later, Aguair designated his mother and then brother as guardians.

Aguiar’s Fort Lauderdale home is valued at $5 million, according to the court petition filed by his mother for control of the estate. His luxury yacht is valued at $2 million. The petition also states he has $25 million in stocks and bonds and $15 million in cash.

“Once he turned 30 and he was given quite a chunk of money for such a young man,” his mother said. “I think it was just extremely overwhelming.”

Ellen Aguiar filed for control of her son’s estate last week, and then amended her petition this week as she asked that a bank, a neutral third party, take control, court records say.

The attorney for Guma Aguiar's wife, Jamie Aguiar, released a statement Wednesday.

"Our foremost concern is to protect the welfare of Jamie Aguiar and her four children. We are reserving comment on the specifics of the ongoing legal action surrounding the estate of Guma Aguiar until after tomorrow's court hearing," attorney William Scherer said.

Guma Aguair's mother described the last four years as “stormy” and said her son was extremely depressed in the last year. His wife told him she was seeking a divorce just before he left on his 31-foot boat the TT Zion on Tuesday of last week.

“I really wanted him to go away for a month, six weeks to get his strength renewed,” she told NBC 6.

Ellen Aguiar also says she discussed getting him help.

“For me, the most important issue was getting Guma to a safe place where he can just take a break from the pressure,” she said. “So I was in touch with different really beautiful facilities. Really he was a person with post-traumatic stress.”

The court documents also say Aguiar has substantial pending litigation both in federal and state court in Florida and New York.
